Step by step solution

01

Peptide

Peptides are short chains of amino acid monomers linked with the peptide bonds. The shortest peptide are said to be di-peptides consisting of 2 amino acids linked by single peptide bond as followed by tri-peptide, tetra-peptide, and so on.

02

Structures of peptides

Phe-Ala, Gly-Gln, Lys-Gly, and R-H are dipeptide which has 2 amino acids with same/different constituent.

(a) Phe-Ala

Structure of Phe-Ala

(b) Gly-Gln

Structure of Gly-Gln

(c) Lys-Gly

Structure of Lys-Gly

(d) R-H

Glutamic acid is synthesized by the following reaction sequence. Draw a stepwise mechanism for Steps [1]–[3].

Question: Identify A and B, isomers of molecular formula \({{\bf{C}}_{\bf{3}}}{{\bf{H}}_{\bf{4}}}{\bf{C}}{{\bf{l}}_{\bf{2}}}\), from the given \({}^{\bf{1}}{\bf{H}}\)NMR data: Compound A exhibits signals at 1.75 (doublet, 3H,\({\bf{J = 6}}{\bf{.9 Hz}}\)) and 5.89 (quartet, \({}^{\bf{1}}{\bf{H}}\),\({\bf{J = 6}}{\bf{.9 Hz}}\)) ppm. Compound B exhibits signals at 4.16 (singlet, 2 H), 5.42 (doublet, \({}^{\bf{1}}{\bf{H}}\),\({\bf{J = 1}}{\bf{.9 Hz}}\)), and 5.59 (doublet, \({}^{\bf{1}}{\bf{H}}\), \({\bf{J = 1}}{\bf{.9 Hz}}\)) ppm.

What steps are needed to convert A to L-dopa, an uncommon amino acid that is effective in treating Parkinson’s disease? These steps are the key reactions in the first commercial asymmetric synthesis using a chiral transition metal catalyst. This process was developed at Monsanto in 1974.
